Is E10 fuel better than unleaded?
E10 petrol is actually a slighter higher octane (94) than regular 91 in a lot of cases, and that can mean your engine performs better. However, ethanol lowers the energy level of the blend by 30%, which means you may experience a slight loss in fuel economy. I can live with that.
Ethanol. Pros: [Reduces demand for foreign oil, low emissions, high octane, and can potentially be produced from waste materials; Ah, the main reason we have been foisted with this stuff.
Good luck to those that filled up yesterday and don't use their cars much.
